Abstract: 1,258,672. Making reinforced metal matrices; welding by pressure. UNITED AIRCRAFT CORP. 20 Aug., 1969 [27 Sept., 1968], No. 41582/69. Headings B3A and B3R. [Also in Divisions C7, E1 and F2] A method of making a metal matrix filament reinforced structural material includes, wrapping a layer of metallic foil on a mandrel 10, winding a filament monolayer on the foil, preheating the mandrel, depositing the metal matrix by plasma arc spraying to encase the filments and form a composite layer, forming additional layers by repeating the steps of winding the filament, preheating and plasma arc spraying and subjecting the multi-layer material to hot pressing. A layer of aluminium or aluminium alloy foil is wrapped around the mandrel 10, which is also of aluminium. The filament may be a fibre of boron, silicon carbide or silicon carbide coated boron, and after it has been wound on to the mandrel, the halves 12, 14 of which are held open by a strap 20, a thumbscrew 23 is released to allow for subsequent relative movement of the halves. The mandrel is then placed in a plasma spray chamber and heated by infra-red heating and the plasma torch in an argon atmosphere to a temperature between 400‹-600‹ F. Aluminium or aluminium alloy powder is sprayed and the heating causes the mandrel 10 to expand against the bias of the springs 18 thereby closing the mandrel pieces 12, 14. As the mandrel cools after spraying, the opposite effect occurs, the mandrel expanding to compensate for the difference in thermal expansion of the fibres and matrix. After cooling, the composite layer is sanded or rolled to provide a smooth surfaced substrate for winding the next fibre monolayer. Alternatively the plasma spraying may be performed in air, in which case the surface is grit blasted, the layers being diffusion bonded. Finally the composite is cut transversely, removed from the mandrel and placed between platens or dies and subjected to a predetermined pressure and temperature. When bonding layers of silicon carbide coated boron fibres in aluminium alloy, full compaction is obtained at 600‹ C. at a pressure of 56À2 kg/cm.<SP>2</SP> or at 550‹ C. and 366 kg/cm.<SP>2</SP> For layers comprising boron fibres in aluminium alloy a pressure of 703 kg/cm.<SP>2</SP> is required at 400‹ C. Preferably the pressing is performed in vacuo or in an argon atmosphere.
